（本经上品）
【气味】苦甘温，无毒。
【主治】主痈疽恶疮，头疡白秃，疥瘙风气，安五脏，除热。久服轻身，不老延年。
【核】曰∶出太山山谷，处处亦有。今以塞上、衡山者为良。其树修耸多节，其皮粗浓
有鳞，其叶凌冬不凋。二三月抽蕤，长三五寸，谓之松黄。放花结实，状如荔枝，叠成鳞砌，
秋老则子长鳞裂，随风飞散，着土便生。其脂通明，宛如薰陆香，以松皮内自然凝聚，及流
结根底，不见日月者为第一，凿取者次之，煮成者不堪用，宜六月采。修治∶用一大釜，釜
中置水，釜上置甑，甑中用白茅藉甑底，更置黄沙于茅上，浓寸许。然后布脂，炊以桑薪，
汤减频加热水。俟脂尽入釜中，乃出之，投于冷水，既凝又蒸，凡三度，则色白如玉，入钵
徐研，钵底置水，方易细。陶贞白云∶采炼松脂法，并在服食方中，以桑灰汁，或酒，煮软，
纳寒水中，数十过，白滑则可用。震亨云∶松脂属阳金，伏汞，制砂，粉银可作匮也。
【 】曰∶松有脂，如人有血，血余则发华不槁，脂余则叶华不凋。松针上指，宛如须
发，心之血分药也。痈疽恶疮，头疡白秃，疥瘙风气，此血中眚，因于血液枯涸，致火气流
亢
合五行，色黄可入脾，坚凝可入肺，长生可入肝，不凋可入肾，味苦气温可入心，五行周
备，故安五脏。若苦能除热，假阴润丽泽之质耳。
（百木夭，其气与液，仅自周其急也。松木寿，岂其自周。其气之余为苓，其液之余
为脂，为珀，咸成不朽。）
【本经上品】
【气味】味苦、甘，性温，无毒。
【主治】主要治疗痈疽恶疮，头部溃疡及白秃（头皮癣），疥疮瘙痒及风邪引起的皮肤病，能安定五脏，清除内热。长期服用可使身体轻盈，延缓衰老，延年益寿。
【考证】曰：松脂出产于泰山山谷中，各地也都有生长。现在以塞上和衡山出产的为优良。松树修长高耸且多节，树皮粗糙厚实且有鳞片，树叶在寒冬也不凋谢。二三月间抽出花穗，长三到五寸，称为松黄。开花结果后，形状像荔枝，层层叠叠如鳞片砌成，深秋时种子成熟鳞片裂开，随风飞散，落在土里就能生长。其树脂透明，宛如薰陆香（乳香），由松皮内部自然凝聚而成，以及流淌凝结在根部，不见日月的为第一等；凿取的次之；煮成的不堪使用，适宜在六月采集。炮制方法：用一个大锅，锅中放水，锅上放蒸笼，蒸笼底铺白茅草，再在白茅草上铺黄沙，厚约一寸。然后将松脂铺在上面，用桑木柴火加热，汤水减少时频繁添加热水。等到松脂全部流入锅中，便取出，投入冷水中，凝固后再蒸煮，共进行三次，则颜色洁白如玉，放入钵中慢慢研磨，钵底加水，才容易研细。陶弘景说：采集炼制松脂的方法，都在服食方中记载，用桑灰汁或酒煮软，纳入冷水中，反复数十次，变得白滑就可以使用了。朱震亨说：松脂属阳金，能伏藏汞，制约砂，使银粉可以做成容器。
【发明】曰：松树有脂，就像人有血，血液充足则头发茂盛不枯槁，脂液充足则树叶繁茂不凋谢。松针向上指，宛如人的须发，是入心经血分的药物。痈疽恶疮，头部溃疡白秃，疥疮瘙痒风邪，这些都是血中的病证，由于血液枯竭，导致火热之气亢盛。结合五行理论，色黄可入脾，坚硬凝固态可入肺，长生特性可入肝，不凋特性可入肾，味苦气温可入心，五行完备，所以能安定五脏。如果苦味能除热，那是借助了阴润滋润的性质罢了。（百木夭折，其气与液，仅能维持自身的急需。松树长寿，难道只是自我维持吗？其气的余气化为茯苓，其液的余液化为松脂、琥珀，都成为不朽之物。）
[Shangpin Category of the Classic of Materia Medica]
[Flavor and Properties] Bitter, sweet, warm, non-toxic.
[Indications] Primarily treats carbuncles, sores, and malignant ulcers; head ulcers and alopecia areata (white baldness); scabies, itching, and wind-pathogen-induced skin diseases; stabilizes the Five Viscera, eliminates heat. Long-term consumption lightens the body, prevents aging, and prolongs life.
[Evidence] It is stated: Pine resin originates from the valleys of Mount Tai, but is also found everywhere. Currently, those from the frontier regions and Mount Heng are considered superior. The pine tree is tall and slender with many nodes; its bark is rough, thick, and scaly; its leaves do not wither in winter. In the second and third lunar months, flower spikes emerge, three to five inches long, called Songhuang (Pine Pollen). After flowering and fruiting, the cones resemble lychees, layered like scales. In late autumn, the seeds mature, the scales split, and they scatter with the wind, taking root when touching the soil. The resin is transparent, resembling Olibanum (Frankincense). It naturally condenses within the pine bark or flows and solidifies at the roots, shielded from sunlight and moonlight; this type is first grade. Those obtained by chiseling are second grade. Those obtained by boiling are unsuitable for use. It should be harvested in the sixth lunar month. Processing: Use a large cauldron filled with water. Place a steamer basket on top of the cauldron. Line the bottom of the steamer basket with white cogon grass (Imperatae Rhizoma), then spread yellow sand about one cun thick on the grass. Spread the resin on top. Cook using mulberry wood fire. Frequently add hot water as the liquid reduces. Wait until all the resin has entered the cauldron, then remove it and throw it into cold water. Once solidified, steam it again. Repeat this process three times until the color is white as jade. Grind it slowly in a mortar. Add water to the bottom of the mortar to facilitate fine grinding. Tao Hongjing said: The methods for harvesting and refining pine resin are recorded in formulas for ingestion. Boil it soft with ash lye from mulberry branches or wine, immerse it in cold water, repeat dozens of times until it becomes white and smooth, then it can be used. Zhu Zhenheng said: Pine resin belongs to Yang Metal; it can subdue Mercury, control Cinnabar, and allow Silver Powder to be made into containers.
[Elucidation] It is stated: Pines have resin just as humans have blood. When blood is sufficient, hair flourishes and does not wither; when resin is sufficient, leaves flourish and do not wither. Pine needles point upward, resembling human beard and hair; thus, it is a herb entering the Heart Blood aspect. Carbuncles, sores, malignant ulcers, head ulcers, alopecia areata, scabies, itching, and wind-pathogen conditions are all ailments within the blood, caused by blood depletion leading to hyperactivity of Fire Qi. Integrating with Five Elements theory: Yellow color enters Spleen; firm and solid nature enters Lung; longevity characteristic enters Liver; non-withering characteristic enters Kidney; bitter flavor and warm temperature enter Heart. With the Five Elements complete, it stabilizes the Five Viscera. If bitterness eliminates heat, it is merely utilizing the moistening and lubricating quality of Yin. (Most trees perish early; their Qi and fluids only suffice for their immediate needs. Pines live long; surely their Qi and fluids do more than mere self-preservation. The surplus of Qi transforms into Poria (Fu Ling); the surplus of fluid transforms into Pine Resin and Amber, all becoming imperishable substances.)
